Uncle Zip’s Beef Jerky is all natural, fresh tasting beef jerky with no additives or preservatives, inspired from an old family recipe. Most commercial beef jerky is full of chemicals that allow it to sit on the shelf for years and also gives the jerky a tough texture. You haven’t really had beff jerky until you had it fresh, the difference is night and day. Ken Howell went into the Shark Tank asking for $25k for 20% of his company. The sharks enjoyed the product but did not invest.
